There was no hiatus in the longterm warming of Earth’s climate.
If you have ever looked at a graph of long-term averages before, you will know that they all have ups and downs, along with a longterm average trend. The global warming “hiatus” from 1998 to 2013 can only be created by ‘zooming in’ on a decade where the increase in average temperatures was was briefly interrupted. (This is also called “cherry picking.”) 1998 was so hot that succeeding years couldn’t keep up, but zooming out to include more years clearly shows that the warming trend has continued unabated, and has even accelerated from 2015 onward.
The fake “hiatus” was part of a strategy developed by a few privately funded think tanks, who are working to sow public doubt and confusion about the established science of global warming. The fact that people are still referring to a supposed “hiatus” shows how sadly effective these disinformation campaigns have been.
